Revision: Surface Chemistry JEE Main Surface Chemistry

Adsorption is the phenomenon of accumulation of a higher concentration of one substance on the surface of another (in bulk) due to unbalanced/unsatisfied attractive forces on the surface.

The phenomenon of increasing the rate of a chemical reaction with the help of a catalyst is known as catalysis.

The phenomenon in which the rate of a chemical reaction is reduced by an inhibitor is called inhibition.

The movement of colloidal particles under an applied electric potential is called electrophoresis.

Multimolecular colloids are species having size in the colloidal range (diameter < 1 nm) that are formed by the aggregation of large number of atoms or small molecules of substances when dissolved in the dispersion medium.

Coagulation is the process by which colloidal particles aggregate and settle as a precipitate. It is brought about by the addition of electrolyte.

It is a process of aggregating together the colloidal particles so as to change them into large-sized particles, which ultimately settle as a precipitate.

The potential difference between a colloidal particle's fixed layer (primary layer) and diffused layer (secondary layer) is known as the zeta potential. It's also referred to as electrokinetic potential.
